    <p>I would like to access listdata.svc (a sharepoint service) located on domainA.contoso.com from a web application located on domainB.contoso.com - Authentication seems to be an issue.</p> <p>When attempting to access ListData.svc via a JQuery Ajax call, with CORS enabled, the server returns 401. If I run the same Query from an .htm page which I execute from inside of SharePoint, the call works fine, since the domain is the same. </p> <p>SharePoint is using NTLM with anonymous authentication turned off - I presume that the 401 is a result of windows credentials not being passed to the SharePoint server - but I am at a loss of how to add these credentials properly to the header. <strong>I have set xhrFields: { withCredentials: true }, but this does not seem to correct the authentication issue.</strong></p> <p><strong>To enabled CORS, I have set the following HTTP Response Headers on SharePoint in IIS:</strong></p> <ul> <li>Access-Control-Allow-Credentials: true </li> <li>Access-Control-Allow-Headers:Origin, Content-Type, Accept </li> <li>Access-Control-Allow-Origin: * </li> <li>Access-Control-Request-Methods: POST, GET, HEAD, OPTIONS</li> </ul> <p>Windows Authentication is enabled in IIS for my web application, and I did not set the "OPTIONSVerbHandler" HTTP Handler in IIS. Turning it to read doesn't seem to make a difference.</p> <p><strong>JQuery Ajax call (from application on subdomainB.contoso.com):</strong></p> <pre><code> $.ajax({ type: "GET", contentType: "application/json; charset=utf-8", url: listUrl, xhrFields: { withCredentials: true }, crossDomain:true, processData: false, async: true, dataType: "json", converters: { // WCF Data Service .NET 3.5 incorrectly escapes singles quotes, which is clearly // not required (and incorrect) in JSON specs. // http://bugs.jquery.com/ticket/8320?cversion=0&amp;cnum_hist=1 "text json": function (textValue) { return jQuery.parseJSON(textValue.replace(/(^|[^\\])\\'/g, "$1'")); } }, success: function (data, status, xhr) { //successFunc(data.d.results); alert("working!"); }, error: function (xhr, status, error) { alert("failure!"); } }); </code></pre> <p><strong>HTTP Header and 401 Response:</strong> </p> <pre><code>Key Value Request OPTIONS /_vti_bin/ListData.svc/Contacts HTTP/1.1 Accept */* Origin http://domainB.contoso.com Access-Control-Request-Method GET Access-Control-Request-Headers content-type, accept Accept-Encoding gzip, deflate User-Agent Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0) Host domainA.contoso.com Content-Length 0 DNT 1 Connection Keep-Alive Cache-Control no-cache Key Value Response HTTP/1.1 401 Unauthorized Server Microsoft-IIS/7.5 SPRequestGuid 1e33061c-f555-451b-9d69-0d83eff5f5ea WWW-Authenticate NTLM X-Powered-By ASP.NET MicrosoftSharePointTeamServices 14.0.0.4762 Access-Control-Allow-Headers Origin, Content-Type, Accept Access-Control-Allow-Origin * Access-Control-Request-Methods POST, GET, HEAD, OPTIONS Access-Control-Allow-Credentials true Date Wed, 15 May 2013 15:04:51 GMT Content-Length 0 </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
